I have a 2007 Mitsubishi Eclipse GT with the 3.8L and have recently experienced power steering issues. I have no power steering until about 2000 RPMs and then after that point it works as it should. I've tried bleeding the system by jacking the front up and steering lock to lock as well as using a vacuum pump and steering from lock to lock. Nothing has seemed to fix it. It was just in the shop last week having the clutch replaced so maybe the mechanic messed something up in the power steering unit in the process?
